DAVID MARVIN MOCRANEY AND SILAS THORLOWV JOHNSON, OF MIN NE- APOLIS, MINNESOTA.

AUTOMATIC MOTOR.

SPECIFICATION forming part of Letters Patent No. 307,785, dated November 11, 1884.

Application filed April 21, 1884. (No model.)

To all whom it may concern.-

Be it known that we, DAVID MARVIN Mo- CRANEY and SILAS Ti-roRLoW JOHNSON, both citizens of the United States, and both residents of Minneapolis, in the county of Hennepin, in the State of Minnesota, havejointly invented certain new and useful Improvements in Automatic Motors, of which the following specification is a full, clear, and exact description, reference being also had to the accompanying drawings, in which Figure 1 is a sectional front elevation. Fig. 2 is a side elevation of our improved motor as applied to operating a churn. Fig. 3 is a det'ail showing a slight variation in the manner of applying the power.

A is the framework, which may be constructed in any desired manner, and having journaled in its upper parts two shafts, a a", on which gears Z) Z) are secured. These gears each mesh into one common pinion, c, on a shaft, (1, parallel with the shafts a (6. Upon this shaft (1, outside the frame A, is a bevelgear, B, engaging with a bevel-pinion, B on an upright shaft, B, running in suitable bearings upon the frame A.

a a a are three shafts j ournaled across the frame A parallel with the shafts a a" and d, and carrying gears b b and pinions I) b, meshing into each other and forming a train of gears connecting the shafts a and a, as shown, and by their sizes causing the shaft a to revolve at an increased speed.

Upon the shaft a is a fan-wheel, O, to serve as a governor to the train of gears, as hereinafter described.

D D are coiled springs, each secured by its inner end to each of the shafts a a and each held by its outer end to studs 9 g in the frame A, as shown.

E E are ratchet-wheels on the shafts a a adapted to be held by pawls h h on the frame A. The shafts a a will have square outer ends 1; 73", so that the springs may be wound.

up by keys in the ordinary manner.-

Suitable stops may be arranged to engage with any of the gears or pinions, to hold them fixed at any point after the springs are wound up and when it is not desired to use their power. By this means the shaft B may be revolved for a length of time corresponding to the lengths of the springs D D", while by means (if the governor C this motion may be regulated and controlled and a steady, uniform motion secured.

The numbersand sizes of the gears and springs may be altered or varied to suit the power required.

We have shown this apparatus arranged to operate a churn dasher, F, on the shaft B working in a churn, G; but it may be used to operate any light machinery or apparatus.

In Figs. 1 and 2 the churndasher is of the revolving style; but by substituting a faceplate, H, with a stud, H moving in a slotted head, 11, in the shaft B, the latter may be moved up and down, instead of revolved, for use where the churn-dasher is of the reciprocating style.

Having described our invention and set forth its merits, what we claim is 1. The combination, in a motor, of two shafts, each provided with a coiled spring, ratchet and paw], and gear wheel, a train of gears, pinions, and counter-shafts connecting one of said spring-shafts with afan-wheel regulator, and a separate shaft carrying a pinion adapted to be acted upon by both ofthe springshat't gear-wheels, substantially as and for the purpose herein specified.

2. The combination of shafts a 66", carrying coiled springs D D" and gears b b, shaft d, carrying pinion 0, adapted to engage with both of said gears, a train of gears, pinions, and counter shafts connecting one of said gears,

I) or b with a fan -wheel governor, (J, and a churn-dasher, F, and churn G, bevel-gear B on the shaft cl, and bevel-pinion B on the dasher shaft 13", whereby the motion of said shaft (Z will operate said churn dasher, substantially'as and for the purpose specified.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
